SPECIFICATION forming part of Letters Patent No. 355,297, dated January e, 187.

Application tiled July 2. 1886. Serial No. 206,902. (No model.)

T aZZ whom, it may concern:

Be it known that l, Lnwis F. Bmrs, of New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Lanterns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and to the letters of reference markedthereon. My invention has relation to that class of lanterns or analogous illuminating apparatus wherein the products of combustion are discharged near or in the region of the point or points at which fresh air for the support of combustion is introduced, the inlet for air and outlet for products of combustion being in close proximity `to secure certain balancing effects during movement of the device, or when subjected to wind-currents, as is now 2o well understood.

Among the objects of my invention are the production of a simple, compact, and efficient lantern or lamp having a closed refiector within the exterior easing, and a passage for 2 5 currents from the exterior to the under side of the burner-cone, provision for balancing or counterbalancing the currents inside and outside the reflector, and to secure other advantages, as will hereinafter appear.

To accomplish all of this my improvements involve certain new and useful peculiarities of construction and'relative arrangements or cornbinations of' parts, all of which will be herein first fully described, and then pointed out in theclaims.

In the accompanying drawings, forming part of' this specication, Figure l is a front elevation, and Fig. 2 a side elevation, of' a hand-lantern constructed and arranged for op- 4o eration in accordance with my invention and involving my improvements. Fig. 8 is a side elevation, and Fig. 4 atop or plan view, of the reflector detached from the exterior easing. Fig. 5 is a vertical axial section. Fig. 6 is a 4 5 cross-section through line x x of Fig. 5. Fig.

7 is a view in side elevation, showing the upper part of the structure turned down to expose the burner for lighting.

In all these figures like letters of reference,

5o Wherever they occur, indicate corresponding parts.

Though the device shown is in the form of' a hand-lantern, it will readily appear that the bail is not necessary, and that the device in its improved form may be used after the manner of any lamp or illuminating contrivance.

A is the oil-fou nt, of which the bottom piece, c, is curved upwardly, to prevent contact, except at the edges, with any object upon which 'the fount may rest. The burner is connected with the top of the fount by a simplejoint, so that it may be readily removed from its seat, and 'the cone B of the burneris perforated at bottom, so as to admit air for the support of combustion.

Gis the exterior casing of the lantern, which inthe example shown is sixsided, but which may be made with any number of sides, or variously curved, as may be desired.

Dis the reflector, secured within the casing by a flange in front anda removable screw, as d, inthe rear, the screw passing through the casing and entering a nut, as b, upon the reflector. Between the reflector and the walls of the casing is an enlarged space for the passage of fresh air-that is, it is enlarged beyond the capacity' of any exposed tubes, such as are ordinarily employed to conduct air-currents in lamps and lanterns. The lower portion o'f the reflector is perforated in such 'manner as to receive the burner-cone, fitting it in a .practically tight or close joint all around, and the upper portion is provided with ashort section of'tube or pipe, D,'locked in place, as by the flanges cl d', and arranged to fit the lower mouthof' the smoke-conduit E. The casing is hinged, as at c, upon an upwardly-extending rim, F, secured upon the oilfount., This 'rim is inclined downwardly to ward the fount, and receives thelower portion of the casing when the latter is locked in place, guiding it properly toward its seat and protecting it from damage or accidental disarrangement.

To expose the burner-cone for trimming the wick or for lighting the burner, the casing is simply to be tipped back, as in Fig. 7. A spring-catch, e, engages with a wire loop, f,

secured upon the easing, and locks the casing The loop f extends down roo in closed position.

beyond the casing far enough to afford conven ient access to spring e, and up along one side far enough to afford substantial abutment for the hinged door to strike against when closed. Y The ratchet-shaft g projects out to one side,

and enters a notch, 7L, in the casing when thelatter is closed to final position.

When the casing is swung back upon its hinge, the reflector clears the cone B withoutv disturbingit.- The cone is of necessity longer than the ordinary forms, so that the flame will tube (through which the products of combustion pass) is a narrow projecting flange, E2, the arrangement being such as to form an efficient ejector at the discharge opening or outlet for products of combustion, so that no matter in what direction the lamp or lantern be moved, or from what direction air-currents may strike it, the el'ect will be to exhaust the contents of the tube E and never to reverse the current in the tube.

Upon the casing C is an upward] y-extendin g tube, F', of slightly larger diameter than E, within which E is secured, and within or through which currents of fresh air flow to the space between the casing and reliector, and thence to the under side of the burner-cone. The upper mouth of this tube is supplied with an injector, G, one part of which depends within the tube and the other part outside of it, the inner portion being slightly removed from the tube E. Upon the sides of F are openings, as fr' i, formed by cutting the mate rial of the tube and bending the flaps t" t" inwardly, substantially as shown. Whenever the lamp is suddenly elevated, air is injected between G and E. Vhen it is suddenly lowered, the overhanging portion of G directs the currents into F, accomplishing like injecting When it is moved or swung in any direction other than vertical, air enters at the openings t' and is turned downwardly by the flaps i', and whatever currents or movements produce injection of fresh air produce also at the same time exhaustion of products of combustion from the smoke-tube, so that, however the device may be moved or exposed, the current of air through the burner-cone is always. in one direction, (upward,) and thus smoking ofthe dame or extinguishment thereof entirely obviated.

. The flange E2 operates, in conjunction with the injector upon tube F', to prevent any current of air (as when the lantern is suddenly lowered) passing so rapidly by the injector as -to create a sufficient vacuum in the region thereoi` to cause the reversal of the current in F. Thus the injector and ejector are made to operate together to sustain the current in the proper direction under all circumstances, and

.tained above F', leaving openings, as at i2 i",

through which fresh air is turned into tube F. These openings i2 might be formed by piercing the material of F. They, together with the openings i i, constitute enlarged inlets, ample for the passage of any desired volume of air much greater than that which is admittedto the exposed separate tubes of previous forms of tubularlanterns,and the injector and ejector ofthe peculiar construction shown are capable of controlling the direction and iniiow of all this air, in consequence of which I am enabled to employ a much larger burner, producing a much larger flame than in the former constructions,wherein burners of small size can only be employed with satisfactory results.

The bail or handle H is applied in sleeves h, which project through F' and E, locking these two parts together. The handle may be removed at any time. j

The door-frame I carries a simple glass pane, K, which closes the front of the reflector. The frame I is hinged to the casing, as at k, upon one portion of the loopf, which forms a convenient hinge-axis. The wire of loopf may extend entirely around the casing, if desired. A spring-catch, Z, serves to lock the door in closed position. The door is mainly intended to be opened when desired to clean the refiector or to remove it, and not for purposes of lighting the burner. To detach the reflector the screw d is removed, the casing tipped back, and the door opened,4 when the reiiector may be easily unseated and withdrawn.

Lis a convenient spring, bent so as to permit any board or other object-such as the' dash-board of a wagon or carriage-to enter between the casing and spring, the lantern being then sustained upon the object, whatever it may be. The inner ends of the spring enter the casing from the top, and the spring may be detached by simply 'd rawing it out of place at any time.

All the parts of the lantern are simple and easyto construct, easy to assemble, and require no expensive machinery for their manufacture. The glass pane, if broken, can be readily replaced by any one.

When constructed in accordance with the above explanations, the lantern or lamp is found in practice to admirably answer all the purposes or objects of the invention previously set forth.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the casing having an air-inject0r at top, the closed reflector fitting over the burner-cone and located within said casing, forming therewith a space or IOO IIO

chamber for the passage of the injected aircurrents to the under side of the burner-cone, the oil-fount, the burner-cone, and the smoketube, the parts being arranged substantially as explained, so that the air-currents inside and outside the reflector will be balanced or counterbalanced, substantially as shown and described.

2. Thecoinbina-tion of the hinged casing, the oil-fount, the burner, the burner-cone, the closed reflector, the smoke-tube connected with the reiiector, and the ejector applied upon the niouth of said tube, the parts being arranged as explained, so as to compel the air to pass from the chamber between the re lector and easing, and up through the cone and reector, substantially as and for the purposes set forth.

casing, the smoke-tube connected with the re- 6. The combination, with the oil-fount, of 4o f the inclined rim applied thereon, and the casing hinged to said rim and arranged to enter the same, substantially as and for the purposes Set forth.

In testimony that I claimthe foregoing I have hereunto set my hand in the presence of two witnesses.
